Sumitomo

Used for most OEM connectors on Subarus.

All connectors seem to be documented to this day on their website including 3D STEP files and CAD drawings which is cool :)
I didn't archive any drawings as they had a notice not to distribute copies of the files.

Connector Kits

2006 Forester 2.5XT EJ255 intake manifold wiring harness connector kit

These are the part numbers for the connectors you need for a stock intake manifold harness.

This equals to the iWire kit KI-SUSTI001-0.
I skipped the oil pressure switch connector as it's just a blade connector at a 90° angle which I couldn't find online. Maybe you have some better luck (or use a basic blade connector). Also the PCV monitoring connector as my EUDM model doesn't have it. And if yours does, just crimp the two pins together. That's all the "sensor" does. The white piece in the PCV monitoring sensor just shorts those two pins to show the ECU it is there lol

I added all these items in AliExpress and ended up with around 70€ + 20€ in shipping. You may be optimize some stuff, or use a more reputable seller for a premium (like Mouser or Corsa-Technic). The main goal is to give you a bill of material to do your own research.

When looking for connectors online make sure to get the correct gender (some of the bulkhead connectors were mixed with female or male on AliExpress for the same connector) and also any keying on the connector (some connectors have keys on the sides, some on the bottom, some none etc.)
